The Future of Voice Assistants and AI, NLP, and Machine Learning

Assignment Task

Abstract

Today the technical industry has made significant advancements, which is increasing day by day. In earlier days there were only computer systems where we were able to perform only few tasks, but today's computer systems are so advanced thanks to new technologies like machine learning, artificial intelligence, deep learning, and a few others that we may use them for any work. Artificial intelligence (AI) has made significant strides recently, and its capabilities are growing every day. Natural Language Processing is a branch of AI that has several applications (NLP). Natural Language Processing (NLP) enables people to interact with computers using their native tongues. As an illustration, voice assistants—also referred to as virtual personal assistants or speech recognition systems—have grown in popularity recently. Many voice assistants have been created, and they are always being enhanced for better performance to overcome people' difficulties interacting with their machines. Python is being used to create a voice assistant that will enable users to complete any activity without needing a keyboard. The purpose of this essay is to examine the intelligent behaviour of voice assistants and how they might be applied to both academic and daily tasks.

Introduction

In today's technological age, machines are replacing humans in every task. Performance changes are one of the primary causes. In the modern world, we teach our machines to think like people and do tasks on their own. As a result, the idea of a virtual assistant emerged. A virtual assistant is a digital assistant that recognises user voice commands and complies with their requests using speech recognition technology and language processing algorithms. A virtual assistant can cut through background noise and return pertinent information based on the user's particular demands. Although virtual assistants are entirely software-based, they are already integrated into a variety of devices. Due to the widespread usage of smartphones, some of the assistants, such as Apple's Siri, Google's Assistant, Microsoft's Cortana, and Amazon's Alexa, are created exclusively for single devices. Voice assistants use voice recognition, speech synthesis, and Natural Language Processing (NLP) technologies to provide a variety of services that allow users to perform tasks on a computer by simply speaking commands into the device. Additionally, using a voice assistant eliminates the need to repeatedly type commands to complete a given task. Owing to the rapid advancement of technology, it is now imperative that we train our machines using deep learning, machine learning, and neural networks. Voice Assistant allows us to communicate with our devices nowadays. Today, every major corporation uses voice assistant technology so that customers can speak to a machine for assistance. Hence, with the Voice Assistant, we are advancing to the stage where we may speak to our machine. These virtual assistants are highly helpful for persons who are elderly, physically or visually impaired, youngsters, etc.

The following are a few of the fundamental things that a voice assistant can aid with: -

• Reading the newspaper
• receiving mail updates
• searching the web
• playing music or videos
• setting reminders and alarms
• using any programme or application
• receiving weather information

These are some of the examples, there are many more things we may accomplish based on our needs. We have created a voice assistant that works with both Linux and Windows users. We created a desktop-based voice assistant that makes use of Python modules and libraries. The current technology is good in that it can still be combined with Machine Learning and the Internet of Things (IoT) for better advancements, but this assistant is simply a basic version that could accomplish all the basic functions that have been discussed above. The fundamental premise of our project is that the user asks the voice assistant to complete their task using the device's microphone, and the command is subsequently translated into text. The text request is processed after that, and a text response is provided along with any voice assistant work. The model was created using Python modules and libraries, and machine learning was used to train it. Certain Windows and Linux instructions were also added to the model to ensure that it would function properly on both operating systems. Our model will mostly operate in three modes: -

1. Supervised Learning.
2. Unsupervised Learning.
3. Reinforcement Learning.

Based on the purpose for which the user needs the aid. And deep learning and machine learning can be used to accomplish these. The Voice Assistant will make it unnecessary for you to repeatedly type commands to carry out specific tasks. Once a model is generated, it can be utilised as many times as necessary by as many people as possible in the simplest manner. Hence, with the aid of a virtual assistant, we will be able to manage numerous aspects of our environment on a single platform.

Reasons for the necessity of voice assistants:

There are many reasons that make this vocal voice command application necessary in practical settings.

These are the few them:

To make it possible for a very engaging user Experience:

No other interface engages consumers as much as voice assistance does. Users can ask for anything they want by speaking naturally to the application.

To simplify the application process:

The current machine system requires us to touch, type, and utilise a mouse to complete our task, which can be frustrating for users at times. With a voice assistant, users can directly ask for the task they want to perform.

To make each user's experience with your app unique:

Indeed, voice assistants are able to answer for each user based on their location, preferred language, and other factors.

To eliminate Linguistic Barriers

Voice assistant technology is combined with translation services, enabling users to interact with them more freely and in their own language without worrying about linguistic boundaries.

Literature Review

Nowadays, we teach our machines to think like humans and do tasks independently, replacing human labour with machinery. Based on this circumstance, the idea of a voice assistant emerges, capable of performing a variety of tasks for people based just on their speech. The virtual assistant can filter out certain user commands and return information that is pertinent to the command.

With emerging technologies like virtual reality, augmented reality, voice interaction, and others, people all over the world are changing how they engage with the internet. As a novel development in human-machine interface, voice control transforms analogue signals into digital waves using spoken signals. The massive growth in the usage of smartphones over the past few years has resulted in widespread use of voice assistants like Apple's Siri, Google's Assistant, Microsoft's Cortana, and Amazon's Alexa, among others. Natural Language Processing (NLP), voice recognition, and speech synthesis are just a few of the technologies used to create voice assistants, which can provide customers a limitless number of applications to make their lives more convenient and comfortable.

According to Deepak Shende, Ria Umabiya, the AIVA (Microsoft, Google Assistant from Google, and the most recent intelligent assistant to come under the moniker "AIVA" 2018) sought to create a voice-controlled personal assistant that is capable of performing numerous tasks, including conducting Internet searches. New features include the ability to quickly and easily publish comments on social media websites like Facebook, Twitter, and others. Also, you can access information about the local climate and the weather.

Tulshan clarified that the user's fingers may suffer injuries as a result of constant typing. To prevent these issues, we must create a system that enables us to complete tasks using voice commands. The system will detect the voice, synthesis the recognised words, and, if they are appropriate or make sense, print them on the screen. The programme will then be assembled and run as a result of the recognition of the specified keywords once more.

Dr. Kshama V. Kulhalli presented that survey amongst the leading speech assistants, including Google Assistant, Siri from Apple, and Cortana from Microsoft. This study came to the conclusion that Google Assistant responses are the most accurate. They could understand the variations in the voice very easily.

Bassam, N. Raja, and others have written about the importance of statements and speeches. The system for human-machine communication used analogue signals that were transformed into digital waves by spoken signals. This technology is widely used, has countless applications, enables machines to respond to user voices accurately and consistently, and provides helpful and appreciated features. The use of speech recognition systems (SRS) is expanding gradually and has endless potential. The investigation has shown the procedure's summary; it is a straightforward model.

Speech analysis is frequently carried out in conjunction with pitch analysis, as indicated by B. S. Atal, L. R. Rabiner, et al. According on the dimensions finished on the signal, the research developed a pattern recognition technique for deciding whether a given slice of a speech signal should be classified as voiced speech, unvoiced speech, or silence. The key limitation of the method is that the algorithm must be tested using a precise set of dimensions and under certain recording conditions.

Technology Used

Python

Python is a high-level, all-purpose programming language that is interpreted.

The voice aid project is being developed using Python 3.6.0.

PyCharm

The most widely used IDE for Python is PyCharm.

Among other fantastic features, it includes excellent code completion and inspection skills, a sophisticated debugger, support for web development, and support for a number of frameworks.

Packages used

Speech Recognition

The purpose of a speech recognition library is to listen to the user's words as they are input via a microphone, process them to determine their meaning, and then convert them into text format. This library enables computer systems to comprehend spoken language.

Pyttsx3

The Python text to speech library, or Pyttsx3, is what we use to speak with our voice assistant. It supports popular text-to-speech engines, a type of software that turns text into speech so that voice assistants may converse with their users. Depending on the requirements, we can have it talk in both male and female voices.

Wikipedia

We have to use Wikipedia library so that we can get information from Wikipedia on any topic or we can also ask for solution to our query or simply we can perform Wikipedia search for any topic using this library. This Python library uses an Internet connection to obtain results, which are then given to the user in both text and speech format.

Datetime

To support the functionality of Date and Time, this module is necessary. This module will be useful to users whenever they need to know the time and date or want to schedule a job for a specific time.

PyAutoGUI

The Python package PyAutoGUI has control over the mouse and keyboard; it can replicate the movement of the mouse cursor and button presses. A specific 2-D coordinate allows us to click on a specific spot on the screen.

PyWhatkit

A Python library called PyWhatKit includes a lot of functionalities, including the ability to send emails, play YouTube movies, convert photos to ASCII, and send messages and images using WhatsApp.

Keyboard

Python's Keyboard module gives users complete control over the keyboard.

The "press ()" and "write ()" functions in particular make it easier to manage the keyboard's keys and type messages on the computer screen.

SpeedTest

To measure internet bandwidth, the SpeedTest library is necessary. It aids in assessing both the uploading and downloading speeds of the Internet. Every response we get is expressed in megabits.

OS

Python's OS (Operating System) module is used to communicate with the operating system. In particular, we open any installed applications in our system utilising the "Start file ()".

Future Works and Limitations

One drawback of our study was that we only used a few databases to find our publications; in future research, we want to use more journal databases, including Scopus and Taylor & Francis. The majority of the experiment studies we gathered were done in controlled conditions; future research will concentrate on usability metrics and independent variables, which are applied in real-world scenarios; additionally, the outcomes can be compared. Further research should be done on objective procedures, including how they might work in conjunction with subjective techniques. This is crucial because it will be crucial to comprehend how strategies complement one another in each usability evaluation as user expectations for voice assistants rise.

Conclusion

In this essay, we discussed a Python-based Voice Assistant. Now, this assistant operates as an application and carries out routine duties like checking the weather, streaming music, searching Wikipedia, opening desktop programmes, etc. The current system's functionality is restricted to working with application-based data only. With the forthcoming versions of this assistant, machine learning will be integrated into the system, producing improved IoT suggestions to operate the adjacent devices in a manner akin to Amazon's Alexa. Voice assistants are probably going to become an increasingly bigger part of our daily lives as technology develops.
